Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on Chevrolet Colorado?
A: You must lift and stabilize your vehicle before starting the Valve Stem Oil Seal and valve spring replacement work. Put the en 46547 into the flywheel teeth after pulling out the service slot plug and lower the vehicle. The next step involves taking out both valve rocker arms and spark plugs. Place the j-44228-a (J-44228-A) base plate over the service cylinder Spark Plug hole. After that put the j 39313 (J 39313) inside the Spark Plug hole while keeping continuous air pressure from closing the valve. Install the j-44228-a elements carefully over the stud holding the chosen valve while taking care of its powerful spring compression. Twist the swivel nut partially to reach the valve locks and then pry out the valve locks with a magnet. Twist the hand nut to reveal the entire arm then move it aside to take out the valve spring retainer and valve spring. Twist and pull the j 38820 (J 38820) tool to replace the old valve stem seal through its gip points. Before sealing the new stem valve apply clean engine oil to both valve surface and inner seal area then use the j 38820 tool to install the new seal. Reposition the valve spring and valve spring retainer while fixing the arm above them then tighten the swivel nut until the valve locks become visible. Use the j 43059 tool to place valve locks and then free the swivel nut and arm of j-44228-a. Follow this procedure on each cylinder valve to lower air pressure and extract the j 39313 piece from the Spark Plug. Raise the car once more and support it to put in the spark plugs and valve rocker arms on the base plate of the j-44228-a. Finally, install the service slot plug and remove the en 46547 from the flywheel teeth to complete the repair.
Q: How to address issues with the Rocker Shaft Spring Kit on Chevrolet Impala?
A: Be certain the Piston at the working cylinder is at top dead center (TDC) before you remove the Valve Stem Oil Seal and valve spring so the valve doesn't fall in. Begin with taking out the Spark Plug by first turning it loose and then brushing away any gunk from the Spark Plug recess. Next, remove the Rocker Arm. Insert the j 22794 (J 22794) into the Spark Plug port, then blast it with compressed air to keep the valve in place. Press the valve spring down using the j 5892-d (J 5892-D) and en-47823 (EN-47823), then take out the valve spring cap keys, the valve cap, the valve spring, and the Valve Stem Oil Seal in order. For assembly, oil the valve stem with clean engine oil, put in the Valve Stem Oil Seal, and confirm the right seals are used: black for intake, brown for exhaust. Put the valve spring and cap in place, then compress the valve spring once more with the j 5892-d (J 5892-D) and the en-47823 (EN-47823). Place the valve cap keys, putting a small amount of grease on them to help keep them in position, and confirm they are seated properly. After the air has been cleared, lift the j 22794 (J 22794) out of the Spark Plug hole, insert the Rocker Arm, and lastly put the Spark Plug back on.
Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on Chevrolet Malibu?
A: Before installing the flywheel holding tool (J 43653) the Crankshaft needs to stay locked in its position because applying compressed air in the cylinder risks hurting the tool. Place vehicles with manual transmission in first gear and activate the parking brake while vehicles with automatic transmission should detach the Starter. Install the flywheel holding tool j 43653 first and remove the Camshaft plus associated roller components. Fit the valve spring compressor tool j 43649 to the cylinder head and take out the spark plugs from each cylinder. Push an air hose connector into the Spark Plug hole until the cylinder reaches 690 kpa (100 psi). To access the valve you must squeeze the spring until you can take off both valve spring keepers and the valve spring. To take out the valve seal use the valve guide seal remover tool j 36017. Insert the valve guide seal remover tool (J 36017) firstly then replace the valve spring to finish the installation. Reapply pressure on the valve spring then put back the spring keepers. Pull out the Spark Plug hose adapter and unfasten valve spring compressor tool j43649 from the cylinder head. Place back the spark plugs along with Camshaft roller followers plus Camshaft. Put back the Starter part if taken out then complete the process by removing the flywheel holding tool (J 43653).
